roan-FEEDING nnvron FOR. FURNACES. I

To all whom it may concern:

Be it known that I, FRANZ PALLENBERG, a 'citizen of the German Empire, and a resident of Dortmund,

Fuel-Feeding Device for Furnaces, of which the following is a full, clear, and exact description The present invention relates to that class of fuel tributing ring having inclined distributing surfaces is mounted to rotate below the hopper.' Some of these rings are provided with distributingsurfaces' having various angles, "5. e. the, angle of inclination differs at different points of the ring, and in this connection the fuel is very liable to take the shortest way over the distributing surface and consequently uneven distribution ensues.

The object of the present invention is to provide means for guiding the fuel properly over the said dis-' tributing surfaces, so that they shall properly fulfil the tributing ring, Fig. 3 is a cross section through the ring on line, C D of Fig. 2,-Fig. 4 is a cross section through the ring on line E F of Fig. 2, Fig. 5 is a vertical central section of a modified form of the apparatuaFig. 6

is a part plan of the same and Fig. 7 is aplan view of the modified formof distributing-ring.

Referring first to Figs. 1 to 4:For the purposes of the present specification. the invention is described as in connection with an ordinary gas generator having I a stack of fuel. 'To the top of the generator, the supporting plate a for the feed deviee is attached. This plate is provided with an outer upwardly extending flange 0. and an inner inclined annular flange a which serve to form a water seal with the downwardly slanting flange b of the carrier plate b for the feed hopper and distributing ring 0. The latter is ,either attached to the plate b or made in one piece with the same. The plate b has an upper horizontal flange provided with ratchet teeth g in which a pawl h engages, so that the said plate b and with it the distributing ring may be turned either by hand or by any suitable driving mechanism. The annular dip formed at the top of the plate b by means of the inner vertical flange 0 forms the water seal for the downwardly extending flangen of the feed hopper l, which may also be supported on the plate a by means of suitable legs l. The hopper lis closed in the known manner by means of thei'ilpper hopper p and the cover to the same.

The distributing ring 0 (Figs. 3 to 4) is in the I Specification of Letters Patent. Application filed June22,1906.. Serial No. 822,982.

tric passage through the same having a vertical wall 0 at one side of the same formed by the eccentricity of the upper surface or plane of the opening as in Fig. 3, thus forming apassage'through the ring having one vertical wall 0 gradually merging into the opposite inclined wall 2:. 'The upper edge of the orifice may be oblong or circular "as shown at Fig 3. The ring is of. a hollow irregular truncated cone having an ecen.

hollow and may be supplied with cooling water through the inlet f (Fig.1): The plate b and thedistribu'ting ring 0 are provided with a suitable number of supporting rolls d adapted to-run on a suitable angle iron or track e, supported on and bolted to the platen, so that 7 of the said ring closes practically against the top of the inclined flange of plate a (Fig. 1). The orifice or through way through the distributing ring is partially closed by a topwall i, whichis so formed that it will 7 5- around the said ring and between it the supporting plate as indicated at y, while the vertical side or part.

. leave a crescent shaped opening as at 2: at the upper I surface ofthe ring, the lower surface of the orifice being c ircular as will be readily understood on refer" .hopper will be evenly distributed through tWdCl'GS- cent shapedopeningsone z revolving with the ring and the'other y being continually formed at successive points around the inclined flange of plate a and betweenitand the outer surface of ring 0. Now in I order to prevent the fuel from taking the shortest cut over the distributing surfaces of the ring c, which is particularly liable with the longer. or less. inclined surfaces, both the interior and exterior distributing surfaces of the said ring are provided with ribs d extending radially down the same, which ribs effectually prevent the fuel from falling off the distributing surfaces, as it were. I

The interior of the hopper is provided with a series of vertically disposed inwardly projecting teeth or flanges m, while the ring 0 is provided with a top cover j in the form of a cone having spirally arranged ribs thereon as at In, which'cooperate with the ribs or teeth m of the hopper l to reduce the pieces of fuel to an uniform size, before they pass through the two crescent shaped openings of the distributing ring.

I The operation of the device is such that when the distributing ring is turned by hand or by suitable mechanism, the fuel will first be reduced to the desired size and will then pass through the outer crescent shaped opening at y to the outer parts of the cross sectional area of the fuel bed and through the enceto Figs. -1 and 3. 'Thus the fuel coming from the opening z in the distributing ring the inner parts of the fuel bed-area, so that the fueIg-will, bythe rotation of the distributing ring, be e venly distribuftd over all the cross sectional area of the bed. Thespir-al ribs 70 serve to feed the fuel to the annular space between the loweredge of the hopper land the outer -edge of the cover 9', through which the fuel passes to the -crescent shapedopenings y and z. The coverj might of course be so arranged or mounted so as to remain stationary and the hopper Z turned' in some suitable manner if desired. i

In the modification shown in Figs. to 7, themrangement of most'oi the partsis substantially tlfe 3 same but the distributing ring is' modified in'iorni.

the slanting wall of the hopper '1, so that it will be evenly distributed .over the central part of the bed, while it will pass over the exterior surface of the ring to the outer parts of the bed in a mann'er similar to that described with reference to Figs. 1 and 2. In

with the guide ribs d. for thepurpose specified. I claim as my invention: y

In a fuel feeding device of the class specified, comprising a hopper having fuel breaking mechanism therein, a rotary distributing ring mounted beneath said hopper, said ring having outwardly incllned distributing Sui-fades of varying inclination, the combination of ribs extending downwardly and spreading outwardly along said distributing s uri ace's.
